Sorry but I can't upload any test file.exe for you to see. I would
advise you to contact your SolidWorks vendor, and ask for
interactive manuls via 3DVia. They surley would be able to send you
some files for you to have a look at and test.

Not sure what your budget is or if you have one, but
Quadrispace works pretty good for a free software. You can do
everything you've mentioned with it. Adobe is another option but
it's going to cost you a little bit. If you have an unlimited
budget 3DVIA would probably be the best option....but again, it's
pricey.
